Abstract

The invention discloses a shooting triggering system suitable for an ultra-high-speed camera in brittle material research. The system comprises a conductive sheet a, a conductive sheet b and an ultra-high-speed camera. Both the conductive sheet a and the conductive sheet b are connected to a copper-silver conductive coating which is applied to the surface of a concrete test piece. The conductive sheet a is connected to a coaxial cable center copper wire, and the conductive sheet b is connected to a coaxial cable mesh conductive layer wire. The joint of the conductive sheet a and the coaxial cable center copper wire and the joint of the conductive sheet b and the coaxial cable mesh conductive layer wire are fixed by staples, and two breakage trigger sensors are formed. The ultra-high-speedcamera is connected to two coaxial cable BNC connectors. The coaxial cable center copper wire and the coaxial cable mesh conductive layer wire are connected to the two coaxial cable BNC connectors through coaxial cables. According to the shooting triggering system, the problem of relying on human triggering and conductive wire triggering of the ultra-high-speed camera in the prior art is solved.

Description

technical field [0001] The invention belongs to the technical field of shooting trigger systems, and in particular relates to a shooting trigger system suitable for ultra-high-speed cameras in the research of brittle materials. Background technique [0002] As far as the prior art is concerned, ultra-high-speed cameras have the characteristics of fast shooting speed and short continuous shooting time. Taking the Kirana 01M ultra-high-speed camera as an example, its minimum shooting rate is 1,000 frames per second, and its maximum rate is 1 million frames per second. It can continuously shoot 180 photos at the highest and minimum shooting rates, and the time-consuming corresponds to 0.18 seconds, and 0.00018 seconds, at this speed, it is almost impossible to manually trigger the camera to capture the image of the moment of crack cracking, so it is necessary to develop a set of ultra-high-speed camera shooting trigger system suitable for the shooting rate of 1000 pictures per ...
